Clinical Trial Summary

The researchers are investigating if changing an individual's behaviors may have an impact on outcomes for patients with pulmonary arterial hypertension (PAH). This research will test the efficacy of a home-based exercise program to improve exercise tolerance and physical activity.

Other	Frequency worsening WHO functional class	WHO functional class higher than previously noted. The World Health Organization (WHO) functional class system was created to define the severity of an individual's symptoms and how they impact on day-to-day activities. The functional classes range from I to IV with IV having worse daily impairments.	12 weeks

Secondary	Efficacy of a home-based exercise training as measured by change in survey score from the EuroQol five dimension, five level (EQ-5D-5L) questionnaire.	Health related quality of life assessed using the EuroQol EQ-5D-5L. There is a descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, extreme problems. The respondent is asked to indicate his/her health state by ticking (or placing a cross) in the box against the most appropriate statement in each of the 5 dimensions.; The survey visual analog scale (VAS) records the respondent's self-rated health on a 20 cm vertical, visual analogue scale with endpoints labelled 'the best health you can imagine' and 'the worst health you can imagine'.; The users guide gives details of the scoring system: https://euroqol.org/wp-content/uploads/2016/09/EQ-5D-5L_UserGuide_2015.pdf	Baseline, 12 weeks

Secondary	Efficacy of a home-based exercise training as measured by change in survey score The Pulmonary Arterial Hypertension-Symptoms and Impact (PAH-SYMPACT)	PAH-SYMPACT (Pulmonary Arterial Hypertension-Symptoms and Impact) is a self-rating questionnaire to assess symptoms and their physical and cognitive/emotional impact. The PAH-SYMPACT™ questionnaire consists of four domains: Cardiopulmonary Symptoms Domain (scored 0-24), Cardiovascular Symptoms Domain (scored 0-20), Physical Impacts Domain (scored 0-28), and the Cognitive/Emotional Impacts Domain (scored 0-16). In each domain a higher score indicates worse symptoms.	Baseline, 12 weeks
